Coating process

 

The coating process seen here is the KTL painting, with a subsequent addition of a wet coating. After zinc phosphating, water-based epoxy resins are added to the intended ROTEX hubs a direct voltage is applied. Next, the painted hubs are baked in a convection oven at temperatures of up to 200° C. The result of this process is a coating which is resistant to numerous solvents, acids and lyes.   

 

The next step towards achieving high corrosion resistant properties is the inclusion of the wet coating. In addition to excellent corrosion protection, other benefits include: greater environmental friendliness, a more consistently even coating thickness,  high temperature resistance,  and greater fit accuracy of the hubs.
